Banking System and Money Supply I. II. Functions of Money A. Medium of exchange: Money can be used for buying and selling goods and services. B. Unit of account: Prices are quoted in dollars and cents. C. Store of value: Money allows us to transfer purchasing power from present to future. It is the most liquid (spendable) of all assets, a convenient way to store wealth. Supply of Money A. Narrow definition of money: M1 includes currency and checkable deposits 1. Currency (coins + paper money) held by public. a. Is “token” money, which means its intrinsic value is less than actual value. The metal in a dime is worth less than 10¢. b. All paper currency consists of Federal Reserve Notes issued by the Federal Reserve. 2. Checkable deposits are included in M1, since they can be spent almost as readily as currency and can easily be changed into currency. a. Commercial banks are a main source of checkable deposits for households and businesses. b. Thrift institutions (savings and loans, credit unions, mutual savings banks) also have checkable deposits. 3. Qualification: Currency and checkable deposits held by the federal government, Federal Reserve, or other financial institutions are not included in M1. B. Money Definition: M2 = M1 + some near-monies which include 1. Savings deposits and money market deposit accounts. 2. Certificates of deposit (time accounts) less than $100,000. 3. Money market mutual fund balances, which can be redeemed by phone calls, checks, or through the Internet. D. Which definitions are used? M1 will be used in this text, but M2 is watched closely by the Federal Reserve in determining monetary policy. 1. M2 and M3 are important because they can easily be changed into M1 types of money and influence people’s spending of income. 2. The ease of shifting between M1, M2, and M3 complicates the task of controlling the spendable money supply. 3. The definition becomes important when authorities attempt to measure and control the money supply. Credit cards are not money, but their use involves short-term loans; their convenience allows you to keep M1 balances low because you need less for daily purchases. A. The government’s ability to keep its value stable provides the backing. B. Money is debt; paper money is a debt of Federal Reserve Banks and checkable deposits are liabilities of banks and thrifts because depositors own them. C. The value of money arises not from anything intrinsic, but its value in exchange for goods and services. 1. It is acceptable as a medium of exchange. IV. V. VI. 2. Currency is legal tender or fiat money. In general, it must be accepted in repayment of debt, but that doesn’t mean that private firms and government are mandated to accept cash; alternative means of payment may be required. (Note that checks are not legal tender but, in fact, are generally acceptable in exchange for goods, services, and resources. Legal cases have essentially determined that pennies are not legal tender.) 3. The relative scarcity of money compared to goods and services will allow money to retain its purchasing power. D. Excessive inflation may make money worthless and unacceptable. An extreme example of this was German hyperinflation after World War I, which made the mark worth less than 1 billionth of its former value within a four-year period. 1. Worthless money leads to the use of other currencies that are more stable. 2. Worthless money may lead to barter exchange system. The Demand for Money: Two Components A. Transactions demand is money kept for purchases and will vary directly with GDP B. Asset demand is money kept as a store of value for later use. Asset demand varies inversely with the interest rate, since that is the price of holding idle money The Money Market: Interaction of Money Supply and Demand Monetary authorities can shift supply to affect interest rates, which in turn affect investment and consumption and aggregate demand and, ultimately, output, employment, and prices. The Federal Reserve and the Banking System A. The Federal Reserve System (the “Fed”) was established by Congress in 1913 and holds power over the money and banking system. 1. The central controlling authority for the system is the Board of Governors, which has seven members appointed by the President for staggered 14-year terms. Its power means the system operates like a central bank. 2. The Federal Open Market Committee (FOMC) includes the seven governors plus five regional Federal Reserve Bank presidents whose terms alternate. They set policy on buying and selling of government bonds, the most important type of monetary policy, and meet several times each year. 4. The system has twelve districts, each with its own district bank and two or three branch banks. They help implement Fed policy and are advisory. a. Each is quasi-public: It is owned by member banks but controlled by the government’s Federal Reserve Board, and any profits go to the U.S. Treasury. b. They act as bankers’ banks by accepting reserve deposits and making loans to banks and other financial institutions. In making loans, the Federal Reserve is the “lender of last resort,” meaning that the Fed is available to lend money should other avenues (e.g., other commercial banks) not be available. 3. About 7,800 commercial banks existed in 2003. They are privately owned and consist of state banks (three-fourths of the total) and large national banks (chartered by the Federal government). 3. Thrift institutions consist of savings and loan associations, credit unions, and mutual savings banks. They are regulated by the Treasury Dept. Office of Thrift Supervision, but they may use services of the Fed and keep reserves on deposit at the Fed. Functions of the Fed and money supply. 1. The Fed issues “Federal Reserve Notes,” the paper currency used in the U.S. monetary system. 2. The Fed sets reserve requirements and holds the reserves of banks and thrifts not held as vault cash. 3. The Fed may lend money to banks and thrifts, charging them an interest rate called the discount rate. 4. The Fed provides a check collection service for banks (checks are also cleared locally or by private clearing firms). 5. The Fed acts as the fiscal agent for the Federal government. 6. The Fed supervises member banks. 7. Monetary policy and control of the money supply is the “major function” of the Fed. C. Federal Reserve independence is important but is also controversial from time to time. Advocates of independence fear that more political ties would cause the Fed to follow expansionary policies and create too much inflation, leading to an unstable currency such as exists in some other countries. Balance Sheet of a Single Commercial Bank A. A balance sheet states the assets and claims of a bank at some point in time. B. All balance sheets must balance, that is, the value of assets must equal the value of claims. 1. The bank owners’ claim is called net worth. 2. Nonowners’ claims are called liabilities. 3. Basic equation: Assets = liabilities + net worth. Money Market and the Interest Rate (Monetary Policy) The Fed has Three Major “Tools” of Monetary Policy: A. Open-market operations refer to the Fed’s buying and selling of government bonds. 1. Buying securities will increase bank reserves and the money supply. a. If the Fed buys directly from banks, then bank reserves go up by the value of the securities sold to the Fed. See impact on balance sheets using text example. b. If the Fed buys from the general public, people receive checks from the Fed and then deposit the checks at their bank. Bank customer deposits rise and therefore bank reserves rise by the same amount. Follow text example to see the impact. i. Banks’ lending ability rises with new excess reserves. ii. The money supply rises directly with increased deposits by the public. c. When the Fed buys bonds from bankers, reserves rise and excess reserves rise by same amount since no checkable deposit was created. d. When Fed buys from public, some of the new reserves are required reserves for the new checkable deposits. e. Conclusion: When the Fed buys securities, bank reserves will increase and the money supply potentially can rise by a multiple of these reserves. The reserve ratio is another “tool” of monetary policy. It is the fraction of reserves required relative to their customer deposits. 1. Raising the reserve ratio increases required reserves and shrinks excess reserves. Any loss of excess reserves shrinks banks’ lending ability and, therefore, the potential money supply by a multiple amount of the change in excess reserves. 2. Lowering the reserve ratio decreases the required reserves and expands excess reserves. The gain in excess reserves increases banks’ lending ability and, therefore, the potential money supply by a multiple amount of the increase in excess reserves. 3. Changing the reserve ratio has two effects. a. It affects the size of excess reserves. b. It changes the size of the monetary multiplier. For example, if ratio is raised from 10 percent to 20 percent, the multiplier falls from 10 to 5. 4. Changing the reserve ratio is very powerful since it affects banks’ lending ability immediately. It could create instability, so the Fed rarely changes it. C. The third “tool” is the discount rate, which is the interest rate that the Fed charges to commercial banks that borrow from the Fed. 1. An increase in the discount rate signals that borrowing reserves is more difficult and will tend to shrink excess reserves. 2. A decrease in the discount rate signals that borrowing reserves will be easier and will tend to expand excess reserves. D. “Easy” monetary policy occurs when the Fed tries to increase the money supply by expanding excess reserves in order to stimulate the economy. The Fed will enact one or more of the following measures: 1. The Fed will buy securities. 2. The Fed may lower the reserve ratio, although this is rarely done because of its powerful impact. 3. The Fed could reduce the discount rate. Although this has little direct impact on the money supply, it is a way for the Fed to “announce” policy direction. E. “Tight” monetary policy occurs when Fed tries to the decrease money supply by decreasing excess reserves in order to slow spending in the economy during an inflationary period. The Fed will enact one or more of the following policies: 1. The Fed will sell securities. 2. The Fed may raise the reserve ratio, although this is rarely done because of its powerful impact. 3. The Fed could raise the discount rate. Although it has little direct impact on money supply, the Fed may use it to “announce” a policy change. F. For several reasons, open-market operations give the Fed most control of the three “tools.” 1. Open-market operations are most important. This decision is flexible because securities can be bought or sold quickly and in great quantities. Reserves change quickly in response. 2. The reserve ratio is rarely changed since this could destabilize bank’s lending and profit positions. 3. Changing the discount rate has little direct effect, since only 2-3 percent of bank reserves are borrowed from Fed. At best it has an “announcement effect” that signals the direction of monetary policy. The strength of this announcement effect will depend on the credibility of the Fed to back up its “announcement” with the other policy tools if necessary. Expansionary or easy money policy: The Fed takes steps to increase excess reserves, which lowers the interest rate and increases investment which, in turn, increases GDP by a multiple amount. Contractionary or tight money policy is the reverse of an easy money policy: Excess reserves fall, which raises interest rate, which decreases investment, which, in turn, decreases GDP by a multiple amount of the change in investment AD/AS Model: I. Introduction to AD-AS Model A. AD-AS model is a variable price model. The aggregate expenditures model in Chapter 10 assumed constant price. B. AD-AS model provides insights on inflation, unemployment, and economic growth. II. Aggregate demand is a schedule or curve that shows the various amounts of real domestic output that domestic and foreign buyers will desire to purchase at each possible price level. 1. It shows an inverse relationship between price level and real domestic output. 2. The explanation of the inverse relationship is not the same as for demand for a single product, which centered on substitution and income effects. a. Substitution effect doesn’t apply within the scope of domestically produced goods, since there is no substitute for “everything.” b. Income effect also doesn’t apply in the aggregate case, since income now varies with aggregate output. 3. What is the explanation of the inverse relationship between price level and real output in aggregate demand? a. Real balances effect: When price level falls, the purchasing power of existing financial balances rises, which can increase spending. b. Interest-rate effect: A decline in price level means lower interest rates that can increase levels of certain types of spending. c. Foreign purchases effect: When price level falls, other things being equal, U.S. prices will fall relative to foreign prices, which will tend to increase spending on U.S. exports and also decrease import spending in favor of U.S. products that compete with imports. B. Determinants of aggregate demand: 1. Changes in consumer spending, which can be caused by changes in several factors. a. Consumer wealth III. b. Consumer expectations c. Household indebtedness d. Taxes 2. Changes in investment spending, which can be caused by changes in several factors. a. Interest rates, b. Expected returns, which are a function of Expected future business conditions Technology Degree of excess capacity Business taxes 3. Changes in government spending. 4. Changes in net export spending unrelated to price level, which may be caused by changes in other factors such as a. National income abroad b. Exchange rates: Depreciation of the dollar encourages U.S. exports since U.S. products become less expensive when foreign buyers can obtain more dollars for their currency. Conversely, dollar depreciation discourages import buying in the U.S. because our dollars can’t be exchanged for as much foreign currency. Aggregate supply is a schedule or curve showing the level of real domestic output available at each possible price level. 1. In the long run the aggregate supply curve is vertical at the economy’s fullemployment output. 2. The curve is vertical because in the long run resource prices adjust to changes in the price level, leaving no incentive for firms to change their output. 1. The short-run aggregate supply curve is upward sloping. 2. The lag between product prices and resource prices makes it profitable for firms to increase output when the price level rises. 3. To the left of full-employment output, the curve is relatively flat. The relative abundance of idle inputs means that firms can increase output without substantial increases in production costs. 4. To the right of full-employment output the curve is relatively steep. Shortages of inputs and production bottlenecks will require substantially higher prices to induce firms to produce. Determinants of aggregate supply: Determinants are the “other things” besides price level that cause changes or shifts in aggregate supply. 1. A change in input prices, which can be caused by changes in several factors. a. Domestic resource prices b. Prices of imported resources c. Market power in certain industries 2. Changes in productivity (productivity = real output / input) can cause changes in per-unit production cost (production cost per unit = total input cost / units of output). If productivity rises, unit production costs will fall. This can shift IV. aggregate supply to the right and lower prices. The reverse is true when productivity falls. Productivity improvement is very important in business efforts to reduce costs. Equilibrium: Real Output and the Price Level A. Equilibrium price and quantity are found where the aggregate demand and supply curves intersect. B. Increases in aggregate demand cause demand-pull inflation 1. Increases in aggregate demand increase real output and create upward pressure on prices, especially when the economy operates at or above its full employment level of output. 2. The multiplier effect weakens the further right the aggregate demand curve moves along the aggregate supply curve. More of the increase in spending is absorbed into price increases rather than generating greater real output. D. Decreases in AD: If AD decreases, recession and cyclical unemployment may result. Employers are reluctant to cut wages because of impact on employee effort, etc. Employers seek to pay efficiency wages – wages that maximize work effort and productivity, minimizing cost. 1. Minimum wage laws keep wages above that level. 2. Menu costs are difficult to implement. 3. Fear of price wars keeps prices from being reduced. E. Shifting aggregate supply occurs when a supply determinant changes. 1. Leftward shift in curve illustrates cost-push inflation –stagflation2. Rightward shift in curve will cause a decline in price level . Exchange Rates and Macroeconomic Policy: I. Financing International Trade A. Foreign exchange markets enable international transactions to take place by providing markets for the exchange of national currencies. B. An American export transaction is explained below. 1. A U.S. firm is selling $300,000 worth of computers to a British firm. 2. Imagine the exchange rate is $2 = 1 Br. pound, so the British firm must pay 150,000 pounds. 3. The British firm will draw a check on its deposit at a London bank for 150,000 pounds, and will send it to the U.S. exporter. 4. The exporter sells the British check to an American bank for $300,000 in exchange for the British check, and the exporter’s account is credited. 5. The American bank will deposit the 150,000 pounds in a correspondent London bank for future sale. 6. Note the major points here. a. Exports create a demand for dollars and a supply of foreign money, in this case British pounds. b. The financing of an American export reduces the supply of money (demand deposits) in Britain and increases it in the U.S. C. An American import transaction example illustrates how a British exporter is paid in pounds while the importer pays dollars. 1. A U.S. firm is buying 150,000 pounds worth of compact discs from Britain. 2. The exchange rate remains at $2 = 1 Br. pound, so the American purchaser must exchange its $300,000 for 150,000 Br. pounds at an American bank—perhaps the same one as in the export example. 3. The American bank will give up its 150,000 pounds in the London bank to the importer, who will pay the British compact discs exporter, who will deposit the money in the exporter’s bank. 4. Again note the major points. a. The financing of American imports reduces the supply of money (demand deposits) in the U.S. and increases it in the exporting country, Britain. b. Imports create a demand for foreign currency (pounds in this case) and a supply of U.S. currency. Flexible Exchange Rates A. Freely floating exchange rates are determined by the forces of demand and supply. 1. The demand curve for any currency is downsloping because as the currency becomes less expensive, people will be able to buy more of that nation’s goods and, therefore, want larger quantities of the currency. 2. The supply curve for any currency is upsloping because as its price rises, holders of that currency can obtain other currencies more cheaply and will want to buy more imported goods and, therefore, will give up more of their currency to obtain other currencies. B. Depreciation means the value of a currency has fallen; it takes more units of that country’s currency to buy another country’s currency. $3 for 1 pound would be a depreciation of the dollar, compared to the original example of $2 per pound. C. Appreciation means the value of a currency or its purchasing power has risen; it takes less of that currency to buy another country’s currency. $1 = 1 pound would be an appreciation of the dollar relative to the pound. D. Determinants of exchange rates are the forces that cause the demand or supply curves to shift. 1. Changes in tastes or preferences for a country’s products would shift the demand for the currency. 2. Relative income changes will cause changes in the demand and supply of currencies. Rising incomes increase the demand for imports, which increases the supply of that country’s currency and the demand for other country’s currencies. 3. Relative price changes will cause changes in the demand and supply of currencies. If American prices rise relative to British prices, this will increase the demand for British goods and pounds; conversely, it will reduce the supply of pounds as British purchase fewer American goods. The theory of purchasing power parity asserts that exchange rates will change to maintain a uniform price in one currency, e.g., dollars, for each product across countries. 4. Changes in relative real interest rates will affect the demand and supply of currencies. Higher U.S. interest rates attract foreign savings; hence, they raise the demand for dollars and reduce the supply of dollars as U.S. investment dollars may remain in this country. IV. 5. Speculation is another determinant. If one believes the value of a currency is about to fall, it will increase the supply of that currency and reduce its demand. Likewise, if one believes the value of a currency is about to rise, it will increase its demand and reduce its supply as people want to hold that currency. Note that such predictions can be self-fulfilling prophecies, since the change in demand is in the direction of the prediction. There are some disadvantages to flexible exchange rates. 1. Uncertainty and diminished trade may result if traders cannot count on future prices of exchange rates, which affect the value of their planned transactions. (However, see Last Word for this chapter for ways in which traders can avoid risk.) 2. Terms of trade may be worsened by a decline in the value of a nation’s currency. 3. Unstable exchange rates can destabilize a nation’s economy. This is especially true for nations whose exports and imports are a substantial part of their GDPs. Fixed Exchange Rates A. Fixed exchange rates are those that are pegged to some set value, such as gold or the U.S. dollar. B. Official reserves are used to correct an imbalance in the balance of payments, since exchange rates cannot fluctuate to bring about automatic balance. This is called currency intervention. C. Trade policies directly controlling the amount of trade and finance might be used to avoid imbalance in trade and payments. D. Exchange controls and the rationing of currency have been used in the past but are objectionable for several reasons. 1. Controls distort efficient patterns of trade. 2. Rationing involves favoritism among importers. 3. Rationing reduces freedom of consumer choice. 4. Enforcement problems are likely as “black market” rates develop. The current exchange rate system is a “managed float” exchange rate system in which governments attempt to prevent rates from changing too rapidly in the short term. For example, in 1987, the then G-7 nations—U.S., Germany, Japan, Britain, France, Italy, and Canada—agreed to stabilize the value of the dollar, which had declined rapidly in the previous two years. They purchased large amounts of dollars to prop up the dollar’s value. The G8 nations (add Russia to the list above) meet regularly to assess economic conditions and coordinate economic policy. 1. In support of the managed float. a. Trade has expanded and not diminished under this system as some predicted it might. b. Flexible rates have allowed international adjustments to take place without domestic upheaval when there has been economic turbulence in some areas of the world. 2. Concerns with the managed float. a. Much volatility occurs without the balance of payments adjustments predicted. b. There is no real system in the current system. It is too unpredictable. VI. Recent U.S. Trade Deficits A. In 2002 the current account deficit in U.S. was a record $504 billion. B. Causes of the trade deficit. 1. From 1995 to 2000 the U.S. economy grew more rapidly than the economies of several major trading nations. This growth of income has boosted U.S. purchases of foreign goods. In contrast, Japan, some European nations, and Canada suffered recessions or slow income growth during this period. 2. Large trade deficits with China have emerged ($83 billion in 2002, larger than the $58 billion U.S. deficit with Japan). 3. Also, a declining savings rate in the U.S. has contributed to U.S. trade deficits and an increase in foreign investment in U.S. C. Implications of U.S. trade deficits 1. A trade deficit means that the U.S. is receiving more goods and services as imports from abroad than it is sending out as exports. The gain in present consumption may come at the expense of reduced future consumption. 2. A trade deficit is considered “unfavorable” because it must be financed by borrowing from the rest of the world, selling off assets or dipping into foreign currency reserves. In 2001, foreigners owned $2.3 billion more assets in the U.S. than Americans owned in foreign assets. 3. Therefore, the current consumption gains delivered by U.S. trade deficits mean permanent debt, permanent foreign ownership, or large sacrifices of future consumption. But it could also mean higher economic growth as foreign investment expands our capital base.
